Abstract
Novel methacrylate ester block polymers comprising both a hydrolyzable and a non-hydrolyzable ester functionality are capable of being partially hydrolyzed and neutralized to yield the corresponding methacrylic acid and methacrylic acid salt (ionomer) derivatives. The compositions are usefully employed in the preparation of thermoplastic elastomers, adhesives and laminating films.
